This year\u2019s International Observe the Moon Night is on Oct. 20. Look for astronomy clubs and science centers in your area inviting you to view the Moon at their star parties that evening!<\/p>\n

<\/p>\n

On Oct. 20, the 11-day-old waxing gibbous Moon will rise in the late afternoon and set before dawn. Sunlight will reveal most of the lunar surface and the Moon will be visible all night long. You can observe the Moon\u2019s features whether you\u2019re observing with the unaided eye, through binoculars or through a telescope.<\/p>\n

Here are a few of the Moon\u2019s features you might spot on the evening of October 20:<\/p>\n

Sinus Iridum\u2014Latin for \u201cBay of Rainbows\u201d\u2014is the little half circle visible on the western side of the Moon near the lunar terminator\u2014the line between light and dark. Another feature, the Jura Mountains, ring the Moon\u2019s western edge. You can see them catch the morning Sun.<\/p>\n

Just south of the Sinus Iridum you can see a large, flat plain called the Mare Imbrium. This feature is called a mare\u2014Latin for \u201csea\u201d\u2014because early astronomers mistook it for a sea on Moon\u2019s surface. Because the Moon will be approaching full, the large craters Copernicus and Tycho will also take center stage.<\/p>\n

Copernicus is 58 miles (93 kilometers) across. Although its impact crater rays\u2014seen as lines leading out from the crater\u2014will be much more visible at Full Moon, you will still be able to see them on October 20. Tycho, on the other hand, lies in a field of craters near the southern edge of the visible surface of the Moon. At 53 miles (85 kilometers) across, it\u2019s a little smaller than Copernicus. However, its massive ray system spans more than 932 miles (1500 kilometers)!<\/p>\n

And if you\u2019re very observant on the 20th<\/sup>, you\u2019ll be able to check off all six of the Apollo lunar landing site locations, too!<\/p>\n

In addition to the Moon, we\u2019ll be able to observe two meteor showers this month: the Orionids and the Southern Taurids. Although both will have low rates of meteors, they\u2019ll be visible in the same part of the sky.<\/p>\n

The Orionids peak on Oct. 21, but they are active from Oct. 16 to Oct. 30. Start looking at about 10 p.m. and you can continue to look until 5 a.m. With the bright moonlight you may see only five to 10 swift and faint Orionids per hour.<\/p>\n

If you see a slow, bright meteor, that\u2019s from the Taurid meteor shower. The Taurids radiate from the nearby constellation Taurus, the Bull. Taurids are active from Sept. 10 through Nov. 20, so you may see both a slow Taurid and a fast Orionid piercing your sky this month. You\u2019ll be lucky to see five Taurids per hour on the peak night of Oct. 10.<\/p>\n

You can also still catch the great lineup of bright planets in October, with Jupiter, Saturn and Mars lining up with the Moon again this month. And early birds can even catch Venus just before dawn!<\/p>\n
